Description
Die Erfindung betrifft eine Bohrvorrichtung mit einer Bohrmaschine, die eine antreibbare, in einem Spindelgehäuse drehbar gelagerte Bohrspindel aufweist, und mit einem an das Spindelende angeschlossenen Bohrfutter, das einen koaxial und drehfest an die Bohrspindel angeschlossenen Futterkörper und Spannbacken umfasst, die relativ zum Futterkörper durch eine gegenüber dem Futterkörper verdrehbare Spannhülse verstellbar sind, ferner mit einer zwischen dem Spindelgehäuse und der Spannhülse vorgesehenen Kupplungseinrichtung, die im eingekuppelten Zustand die Spannhülse in Umfangsrichtung kraftschlüssig mit dem Spindelgehäuse verbindet.The Invention relates to a drilling device with a drill, which has a drivable, rotatably mounted in a spindle housing drill spindle, and with a chuck connected to the spindle end, the a coaxial and rotationally fixed to the drill spindle connected chuck body and Clamping jaws comprising, relative to the chuck body by a relative to the Chuck body rotatable clamping sleeve are adjustable, further with a between the spindle housing and the clamping sleeve provided coupling device in the engaged state the clamping sleeve non-positively in the circumferential direction with the spindle housing combines.
Aus
der
Der Erfindung liegt daher die Aufgabe zugrunde, eine Bohrvorrichtung der eingangs genannten Art so auszubilden, dass durch Ausnutzung der Präsenz der Kupplungseinrichtung ein weiter gesteigertes Sicherheitsniveau erreicht wird.Of the Invention is therefore based on the object, a drilling device of the type mentioned above in such a way that by exploitation the presence the coupling device a further increased security level is reached.
Diese Aufgabe wird nach der Erfindung bei einer Bohrvorrichtung der eingangs genannten Art dadurch gelöst, dass eine gegen Verdrehen gesicherte Schutzhülse die Spannhülse überdeckt, und dass zur Einspeisung des Kühlluftstroms der Bohrmaschine in das von der Schutzhülse umfasste Volumen eine Austrittsöffnung in dem Spindelgehäuse ausgebildet ist.These The object is according to the invention in a drilling device of the above solved by the type mentioned, that a protective sleeve secured against rotation covers the clamping sleeve, and that for feeding the cooling air flow the drilling machine in the volume covered by the protective sleeve has an outlet opening in formed the spindle housing is.
Bei dieser Bohrvorrichtung sind die durch den Spindelantrieb drehenden Teile der Bohrvorrichtung mittels der Schutzhülse abgeschirmt, so dass als drehendes Teil nur das Bohrwerkzeug aus der Bohrvorrichtung hervorragt, während das Bohrfutter gekapselt ist und somit weder den Nutzer verletzen noch das zu bearbeitende Werkstück beschädigen kann, wenn beispielsweise beim Durchbohren ein direkter Kontakt zwischen dem Werkstück und der Bohrvorrichtung hergestellt wird. Allerdings ist zu beachten, dass durch die Kapselung des Bohrfutters Bohrklein und Bohrstaub nicht wie in gewohnter Weise durch die Zentrifugalkraft nach außen transportiert werden kann, um so einer Verschmutzung des Bohrfutters vorzubeugen. Um dieses Problem zu beseitigen, sieht die Erfindung vor, dass der bei der Bohrmaschine stets präsente Luftstrom genutzt wird, um dem Eindringen des Bohrstaubes entgegenzuwirken, indem der Kühlluftstrom von dem Spindelgehäuse in das von der Schutzhülse umfasste Volumen eingespeist wird, der eine Gegenströmung zu der üblichen Förderrichtung des Bohrstaubes bereitstellt.at This drilling device are rotating through the spindle drive Shielded parts of the drilling device by means of the protective sleeve, so that as rotating part protrudes only the drilling tool from the drilling device while the Chuck is encapsulated and thus neither hurt the user nor the workpiece to be machined can damage for example, when piercing a direct contact between the workpiece and the drilling device is manufactured. However, it should be noted that by the encapsulation of the drill chuck cuttings and Bohrstaub not be transported outwards in the usual way by the centrifugal force so as to prevent soiling of the drill chuck. Around To overcome this problem, the invention provides that the always present in the drilling machine Air flow is used to counteract the penetration of Bohrstaubes by the cooling air flow from the spindle housing in the of the protective sleeve enclosed volume is fed, which is a countercurrent to the usual conveying direction of the drilling dust.
Um möglichst effektiv den Luftstrom auszunutzen, ist im Rahmen der Erfindung vorgesehen, dass die Austrittsöffnung innerhalb der radialen Ausdehnung der Schutzhülse platziert ist, also der Kühlluftstrom unmittelbar in die Schutzhülse hineinströmen kann und nicht nur mit einem geringen Wirkungsgrad die an seitlichen Lüftungsschlitzen des Spindelgehäuses austretende Kühlluft radial von außen in die Schutzhülse eingekoppelt werden muss.Around preferably to effectively utilize the air flow is within the scope of the invention provided that the outlet opening is placed within the radial extent of the protective sleeve, so the Cooling air flow directly into the protective sleeve pour in can and not only with a low efficiency of the lateral vents of the spindle housing exiting cooling air radially from the outside in the protective sleeve must be coupled.
Ganz besonders bevorzugt ist es dabei, wenn der in die Schutzhülse eingekoppelte Luftstrom zwischen der Schutzhülse und der Spannhülse axial nach vorne in Richtung der Spannbacken geführt ist. Durch diese Ausführungsform werden besonders effektiv die Auswirkungen gemildert, die entstehen, wenn der mit üblichen Maßnahmen aus dem Bohrfutter herausgeführte Bohrstaub auf die Schutzhülse als Hindernisse trifft, weil der Luftstrom den Bohrstaub aus dem Spalt zwischen der Spannhülse und der Schutzhülse wieder hinausbefördert.All It is particularly preferred if the coupled into the protective sleeve Air flow between the protective sleeve and the clamping sleeve is guided axially forward in the direction of the jaws. By this embodiment It is particularly effective in mitigating the effects that arise when the usual activities led out of the drill chuck Drilling dust on the protective sleeve as obstacles, because the air flow from the drilling dust Gap between the clamping sleeve and the protective sleeve again transported out.
Eine besonders effektive Förderung des Bohrstaubes aus der Spannhülse in den Zwischenraum zwischen der Spannhülse und der Schutzhülse wird erreicht, indem in der Spannhülse radial Entstaubungsöffnungen ausgebildet sind.A particularly effective promotion the drilling dust from the clamping sleeve in the space between the clamping sleeve and the protective sleeve is achieved by putting in the clamping sleeve radial dedusting openings are formed.
Alternativ besteht auch die Möglichkeit, dass die Austrittsöffnung innerhalb der radialen Ausdehnung der Spannhülse platziert und der Luftstromm innerhalb der Spannhülse axial nach vorne in Richtung der Spannbacken geführt ist. Bei dieser Ausführungsform wird zum einen einem vermehrten Eindringen von Bohrstaub in das von der Spannhülse umhüllte Bohrfutter entgegengewirkt, was insbesondere auch die Ansammlung von Bohrstaub innerhalb des Bohrfutter vermeidet. Einer Ansammlung von Bohrstaub zwischen der Schutzhülse und der Spannhülse wird daher indirekt und vorbeugend entgegengewirkt.alternative there is also the possibility that the outlet opening placed within the radial extent of the collet and the airflow within the clamping sleeve is guided axially forward in the direction of the jaws. In this embodiment becomes on the one hand an increased penetration of Bohrstaub in the from the clamping sleeve sheathed Chuck counteracted, which in particular also the accumulation of drilling dust within the chuck. A collection of drilling dust between the protective sleeve and the clamping sleeve is therefore indirectly and preventively counteracted.
Um dabei eine möglichst gezielte Führung des Luftstromes innerhalb des Bohrfutters zu erzielen, ist in den das Bohrfutter bildenden Bauteilen mindestens ein Luftleitkanal ausgebildet, der insbesondere dazu dient, die axiale Erstreckung des Bohrfutters zu überbrücken, um die axial hinteren und axial vorderen Hohlräume des Bohrfutters miteinander zu verbinden.In order to achieve the most targeted guidance of the air flow within the chuck, at least one air duct is formed in the chuck forming components, which serves in particular to bridge the axial extent of the chuck to the axially rear and axially front cavities of the chuck with each other to connect.
Insbesondere wenn bei einem nachspannenden Bohrfutter mit der durch einen Spannkonus und einen Backenhalter gebildeten Spannhülse sowie einem die Spannbacken radial führenden, in ein zentrales Körpergewinde des Futterkörpers mit einem Mitnehmergewinde eingreifenden Mitnehmer die Gestaltung so getroffen ist, daß der Luftleitkanal in dem Mitnehmer ausgebildet ist, ist eine Zuführung des Luftstroms entlang der zentralen Achse des Bohrfutter zu dem Ort der Einspannung des Bohrwerkzeuges und damit auch in die Nähe der Erzeugung des Bohrstaubes einfach möglich. Dazu ist es günstig, wenn der Luftleitkanal den Mitnehmer über dessen gesamte axiale Länge durchsetzt.Especially if in a chucking chuck with the through a clamping cone and a jaw holder formed clamping sleeve and a clamping jaws radially leading, in a central body thread of the chuck body with a driver thread engaging driver the design so taken that the Air duct is formed in the driver is a supply of the Air flow along the central axis of the chuck to the place the clamping of the drilling tool and thus in the vicinity of the generation of drilling dust easily possible. It is convenient for this when the air duct passes through the driver over its entire axial length.
Ergänzend besteht die Möglichekeit, daß der Luftleitkanal in dem Mitnehmer mindestens einen radial verlaufenden Zweig aufweist, um nicht nur dem Eintreten des Bohrstaubs entgegenwirken, sondern auch dessen Entfernen aus dem Bohrfutter bewirken zu können.Complementary exists the possibility, that the air duct in the driver has at least one radially extending branch, to counteract not only the entry of the drilling dust, but also its removal from the drill chuck cause.
Verluste in der radialen Strömung werden vermieden, wenn am axial vorderen Ende zwischen der Schutzhülse und der Spannhülse eine Dichtungsstruktur realisiert ist.losses in the radial flow be avoided if at the axial front end between the protective sleeve and the clamping sleeve a sealing structure is realized.
Insbesondere wenn bei einem nachspannenden Bohrfutter mit der durch einen Spannkonus und einem Backenhalter gebildeten Spannhülse ein derartiger Luftleitkanal vorgesehen ist, ist es günstig, dass der Luftleitkanal durch den Backenhalter zu den Spannbacken geführt ist.Especially if in a chucking chuck with the through a clamping cone and a jaw holder formed clamping sleeve such an air duct is provided, it is favorable that the air duct is guided by the jaw holder to the clamping jaws.
Als vorteilhaft hat es sich weiterhin erwiesen, wenn in der Schutzhülse eine radiale Austrittsöffnung ausgebildet ist, die den direkten Austritt des Bohrstaubes aus dem Zwischenraum zwischen der Spannhülse und der Schutzhülse ermöglicht.When Advantageously, it has also proven to be in the protective sleeve a formed radial outlet This is the direct exit of the drilling dust from the gap between the clamping sleeve and the protective sleeve allows.
